Re: Time match in mangle/POSTROUTING?

[Patrick McHardy <kaber@trash.net>]

POSTROUTING packets don't neccessarily have a timestamp since packets are
stamped when they are received which doesn't happen for locally generated
traffic. In the source I can see an option "kerneltime" which uses
gettimeofday, this should work fine in any chain. The patch does work in
OUTPUT, it uses kerneltime automatically then (and also unneccesarrily
in FORWARD). A correct fix would require using kerneltime in OUTPUT
and POSTROUTING and the skb stamp otherwise.

Best regards,
Patrick
